Wordpress (I'm evaulating this for a suitable Joplin replacement ) In short - I found that it's easier to reference a site instead of installing Joplin when I rebuild my computer.
Psono password manager
You may wonder why I am using Zitadel and Authentik, I first started with Zitadel, and moved to Authentik, but am evaluating both. They both have their positives. So far Authentik has been the most useful for me. And about the two password managers, I use Vaultwarden as it supports everything I need including Passkey support. My step daughter who is an adult is disabled so having an easier password like Psono makes it easier for her.
I'm not a Wyze subscriber and just use the cams for monitoring. The Wyze Cam Pan 3 so far has been quite amazing with low light full color pics whereas my Pan Cam 2 is just black and white in same low light.
With the bridge, you can pipe the feed it provides to Shinobi or another DVR which reads RTSP, RTMP or HLS feeds and saves them to your storage for full time recording so you don't need the subscription. You do have to login to your Wyze account for the bridge to work though but that's fine with me.
Because, for Home Assistant, I moved it from Raspberry Pi 4 to a KVM and found it faster. I use Proxmox for that which I found to play nicer with it than just setting up a Debian Server and spinning up a KVM via QEMU on a desktop. I've been there and had issues over time. As for why LXC's they are smaller and the only ones I use are from https://tteck.github.io/Proxmox/ which makes them super simple to set up and run!
Can't speak for OP but I can say that I switched to proxmox from just running docker and services native. Proxmox offers a lot of flexibility, you can do snapshots, build many different LXC containers very easily, to keep things separate or have better control over resource usage. Also I run mine in a 3 node cluster so I can do live migration of VMs and pretty quick migrations of LXC containers. This all allows me to run my services with little to no downtime and have redundancy.
